JAMES R. CARTER, OF WEST NEWTON, MASSACHUSETTS.

PROTECTOR FOR MILK-BOTTLES.

To all whom it may concern:

Be it known that I, JAMES R. CARTER, of "West Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Protector-s for Mills-Bottles, of which the following is a specification.

-lhe most common receptacle for milk in use at prese'ht comprises a bottle which is closed .by a disk stopper which rests upon an internal seat of the neck, somewhat below the top. Such location of the disk stopper is necessary in order that it shall retaln its position, but it results in leaving a space which catches dust and dirt and frequently holds a small quantity of spilled milk that sometimes results in stray cats and dogs licking the top of the bottle. This is of.

course objectionable. When the disk stopper is removed some dirt is liable to fall into the bottle, and frequently some remains adhering to the inner surface of'the glass around the top and the milk when poured out must flow over said dirt and isof course liable to carry said dirt with it. The object of m invention is to provide a protcctor whlch reliably prevents either access of dirt to the space above the disk sto per and will also prevent any animal from icking the to Preferably-my improved protector is used in addition to the disk stopper, although it may be used without such stopper,.or may be used to cover a partially filled bottle from which the disk stopper has been removed, and a portion of t e contents poured out.

To these ends my invention consists in the protector and the combination of it with the milk bottle, substantially as hereinafter described and claimed.

Of the accompanying drawings,"Figure 1 is a side elevation of the upper portionof a milk bottle provided with my improved Fig. 2 is a section on line 2--2 of Fig. 1. Fig. 3 is a diagram to indicate the shape of the 'crimps preferably imparted to the skirt. Fig. 4 is a detail section illustratin the use of a contractile ring or band carrie by the protector. u

Similar reference characters indicate the same or similar parts in ,all of the views.

The upper portion of a milk bottle of ordinary construction is indicated at 5, said bottle having an internal annular shoulder Specification of Letters Iatent.

6, forming a seat for the margin of an ordinary form of disk stopper 7 which is usually of paste board. The outer portion of the top' of the bottle is formed with an annular external curved or rounded rib 8. The. extreme top of the bottle is formed .with an inner bevel 9, which in practice'facilitates the placing of the disk stopper 7 in position, the upper portion of the rounded rib 8 presenting an outer bevel 10. Such bottles and disk stoppers are well known.-

My invention comprises a paper cap having a flat top 11, and a crimped skirt 12, the margin 13 of which is also crimped and turned outwardly and upwardly, said crimped margin reinforcing the edge of the skirt and increasin its contractile force. In order to insure t e proper fittingot the paper cap, and its retention in place, a sprin wire ring 14 is fitted within the upturne margin as shown in Fig. 4;. lln order that the contractile rin 1.4 may be placed in position if desired, a ter the cap has been.

located on the bottle top, the margin 13 of the skirt 12 is turned outwardly, and upwardly, as has been described. If said margin were turned inwardly instead of outwardl the ring 14 could not be easily place in position, and if it should slip out after the cap is in place, the cap would have to be removed and the ring I'Q HISBIiZGd, in a manner that would require" considerable time and efiort. Owing to the fact'that the margin 13 of the skirt is turned outwardly and u wardly, the said margin presents no obstac e to a close fit over an extended area of the annular bottle rib, as clearly shown in Fig. 2, thereby preventin any possibility of dirt being forced by win 6. pressure inside of the protector. In practice, the normal diameter inside of the inargin 13 when the protector is not on abottle is such that when the protector is being applied to position, the lower edge of the margin of the skirt Wlll so engage the outer bevel 10 that downward pressure will cause the edge of the skirt to be distended.
